I'll bite: yes. If you show me images of goatse or mutilated bodies in a war zone without my consent that’s mind rape. Same with bring politics forcibly into the workplace, showing Fox News (or MSNBC or whatever) at the bbq joint while I’m trying to eat or at the gym while I’m trying to exercise, or screaming at me in protest while I’m trying to access family planning services.
Just like women have the right to walk down the street in whatever clothing they want without getting raped, I have the right to experience the world without constantly being bombarded by commercial and political mind rape.
> If not, where do you personally draw the line?
Consent is implicit via set and setting. If you want to challenge peoples viewpoints go to college or start a poker night with a bunch of philosophically diverse neighbors who like to argue politics. If you want to shove ads down everyone's throat, go join an influencer support group.
Everyone else deserves to live free from constant mental assault.
> And, just as importantly, who do you feel should get to decide in the general case?
Judges, the people who interpret laws.
